Huge fire burns Fremont metal plant, prompts chemical concerns

A worker from a nearby business covers his face from thick smoke as he is escorted by a firefighter away from a building on fire Tuesday, Sept. 30, 2014, in Seattle's Fremont neighborhood. No injuries were reported from the fire, which sent flames bursting through the roof of the building and created a large plume of smoke visible from downtown. (AP Photo/Elaine Thompson)
